What an impressive dig. Its wonderful they spent the money to bury the parking on this site, its just too important and visible of a place to stick an ugly podium.
I'm surprised to see it go so deep with sheet pilings. Must be possible with those heavy reinforcements, I dont remember the sheet piles being this long when they drove them in.
I remember reading that One Chicago Square will have such deep parking they cant even use sheet piles. They are going with the more expensive secant wall on that site.
